Utility–Privacy Trade-Offs with Limited Leakage for Encoder
Entropy, 2023 The utilization of databases such as IoT has progressed, and understanding how to protect the privacy of data is an important issue. As pioneering work, in 1983, Yamamoto assumed the source (database), which consists of public information and private ...

Average Redundancy for Known Sources: Ubiquitous Trees in Source Coding [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 Analytic information theory aims at studying problems of information theory using analytic techniques of computer science and combinatorics. Following Hadamard's precept, these problems are tackled by complex analysis methods such as generating functions,

Coding in Diffusion-Based Molecular Nanonetworks: A Comprehensive Survey
IEEE Access, 2023 Diffusion-based molecular nanonetworks exploit the diffusion of molecules, e.g., in free space or in blood vessels, for the purpose of communication. This article comprehensively surveys coding approaches for communication in diffusion-based molecular ...

DeepJSCC-f: Deep Joint Source-Channel Coding of Images With Feedback [PDF]
IEEE Journal on Selected Areas in Information Theory, 2019 We consider wireless transmission of images in the presence of channel output feedback. From a Shannon theoretic perspective feedback does not improve the asymptotic end-to-end performance, and separate source coding followed by capacity-achieving ...

Deep Learning for Joint Source-Channel Coding of Text [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2018 We consider the problem of joint source and channel coding of structured data such as natural language over a noisy channel. The typical approach to this problem in both theory and practice involves performing source coding to first compress the text and

Hyperspectral Pansharpening Based on Homomorphic Filtering and Weighted Tensor Matrix
Remote Sensing, 2019 Hyperspectral pansharpening is an effective technique to obtain a high spatial resolution hyperspectral (HS) image. In this paper, a new hyperspectral pansharpening algorithm based on homomorphic filtering and weighted tensor matrix (HFWT) is proposed ...

Structure Tensor-Based Algorithm for Hyperspectral and Panchromatic Images Fusion
Remote Sensing, 2018 Restricted by technical and budget constraints, hyperspectral (HS) image which contains abundant spectral information generally has low spatial resolution. Fusion of hyperspectral and panchromatic (PAN) images can merge spectral information of the former

Polar codes for distributed source coding [PDF]
Electronics Letters, 2013 A polar coding method to construct a distributed source coding scheme which can achieve any point on the dominant face of the Slepian‐Wolf rate region for sources with uniform marginals is proposed.

Exponent function for one helper source coding problem at rates outside the rate region [PDF]
International Symposium on Information Theory, 2015 We consider the one helper source coding problem posed and investigated by Ahlswede, Körner and Wyner. In this system, the error probability of decoding goes to one as the source block length n goes to infinity.
